A team of astronomers led by Caltech has discovered a new type of supernovae that was previously unknown. The four newly found supernovae have similar spectral signatures, indicating they are all part of the same class. This discovery provides insight into star formation, distant galaxies, and the early universe.
Researchers found five to ten times more massive galaxies existed 1.5 billion years after the Big Bang, with high infrared luminosities indicating intense growth and activity, challenging current understanding of galaxy formation.

Physicists at the University of Innsbruck suggest that ball lightning observations may be caused by phosphenes induced in the brain by strong magnetic fields. These fields can produce sensations such as noises or smells and are similar to transcranial magnetic stimulation (TMS) used in clinical practice.
A team of astronomers has found a sample of massive galaxies with properties suggesting they may have formed recently, running counter to widely-held beliefs. The discovery challenges our understanding of galaxy formation and evolution, offering new opportunities for research into the origin and early history of galaxies.
Astronomers have witnessed a star dying in real-time for the first time, marking a major breakthrough in understanding supernovae. The team used NASA's orbiting Swift telescope to detect an extremely luminous X-ray blast from the explosion, confirming that it was indeed a supernova.

A team of researchers proposes a new mechanism to explain the brightest ever recorded supernova, SN 2006gy. The model suggests that an extremely massive star undergoes repeated explosions, resulting in a display up to 100 times more luminous than usual.
Researchers found that synesthetes' experience brighter colors when seeing or thinking of frequently used digits. This effect is not limited to synaesthetes, as non-synaesthetes also associate more luminous colors with common digits.
Researchers used COSMOS field data to measure large-scale distribution of matter, revealing concentration of luminous and dark matter. The 3D map provides insight into the formation and evolution of galaxies and may shed light on dark energy.
Astronomers used VISIR instrument to map infrared disc around young, massive star HD 97048, finding it at least 12 times larger than Neptune's orbit. The disc is flared and contains a large amount of gas, potentially hosting planetary embryos.

The simulations accurately reproduced the distribution of galaxies in the early stages of the universe's evolution.
Researchers have created a massive 3-D map of the universe, mapping the distribution of galaxies and providing new insights into dark energy. The map uses luminous red galaxies as 'lighthouses' to measure distances, covering vast scales of up to a billion light-years across.
Fermilab's Tevatron collider has achieved a record-breaking luminosity of 872 inverse picobarns, producing an unprecedented number of collisions. The collider's high-energy performance is expected to enhance the chances for scientific discoveries before the Large Hadron Collider takes over in 2007.
Researchers observed a Transient Ionospheric Glow Emission in Red (TIGER) event in the Indian Ocean, defying known luminous events. The event's unusual characteristics suggest an extraterrestrial origin, with no clear explanation for its cause.
The team discovered LBV 1806-20, a massive star at least 150 times larger than the sun, with estimated age of less than 2 million years. The star's enormous size is attributed to shock-induced star formation, while its location in a rare cluster of stars raises further questions about its origins.
Brown dwarf Cha Ha 1 is the youngest known member of the Chamaeleon dark cloud, with a mass of 4-5% of the Sun's mass and an age of one million years. Its X-ray emission was detected using the ROSAT satellite.
